Higgs boson in a flavor-extension of the CMSSM

Surabhi Gupta, Sudhir Kumar Gupta, Keven Ren

Flavour-violating couplings of Higgs boson with stop and scharm quarks could be very important as in addition to lifting the mass of the Higgs boson by a few GeV, it could also pla…

A Physical Model for the Quasar Luminosity Function Evolution between Cosmic Dawn and High Noon

Keven Ren, Michele Trenti

Modeling the evolution of the number density distribution of quasars through the Quasar Luminosity Function (QLF) is critical to improve our understanding of the connection between…

The Diversity of Environments Around Luminous Quasars at Redshift

Keven Ren, Michele Trenti, Madeline A. Marshall +2

Significant clustering around the rarest luminous quasars is a feature predicted by dark matter theory combined with number density matching arguments. However, this expectation is…

Two-Loop anomalous dimensions of QCD operators up to dimension-sixteen and Higgs EFT amplitudes

Qingjun Jin, Ke Ren, Gang Yang

We consider two-loop renormalization of high-dimensional Lorentz scalar operators in the gluonic sector of QCD. These operators appear also in the Higgs effective theory obtained b…

Limits to Rest-Frame Ultraviolet Emission From Far-Infrared-Luminous z~6 Quasar Hosts

Madeline A. Marshall, Mira Mechtley, Rogier A. Windhorst +20

We report on a Hubble Space Telescope search for rest-frame ultraviolet emission from the host galaxies of five far-infrared-luminous quasars and the hot-dust…

Stochastic Processes as the Origin of the Double-Power Law Shape of the Quasar Luminosity Function

Keven Ren, Michele Trenti, Tiziana Di Matteo

The Quasar Luminosity Function (QLF) offers insight into the early co-evolution of black holes and galaxies. It has been characterized observationally up to redshift with…

The Impact of Scatter in the Galaxy UV Luminosity to Halo Mass Relation on Ly Visibility During the Epoch of Reionization

Lily R. Whitler, Charlotte A. Mason, Keven Ren +5

The reionization of hydrogen is closely linked to the first structures in the universe, so understanding the timeline of reionization promises to shed light on the nature of these…

The Brightest Galaxies at Cosmic Dawn from Scatter in the Galaxy Luminosity versus Halo Mass Relation

Keven Ren, Michele Trenti, Charlotte A. Mason

The Ultraviolet Luminosity Function (UVLF) is a key observable for understanding galaxy formation from cosmic dawn. There has been considerable debate on whether Schechter-like LFs…

The Cosmic Web Around The Brightest Galaxies During The Epoch Of Reionization

Keven Ren, Michele Trenti, Simon J. Mutch

The most luminous galaxies at high-redshift are generally considered to be hosted in massive dark-matter halos of comparable number density, hence residing at the center of overden…

Derivation of the effective Chiral Lagrangian for pseudoscalar, scalar, vector and axial-vector mesons from QCD

Ke Ren, Hui-Feng Fu, Qing Wang

A previous formal derivation of the effective chiral Lagrangian for low-lying pseudoscalar mesons from first-principles QCD without approximations [Wang et al., Phys. Rev. D61, (20…
